NettetBroadcast Channel with Imperfect Channel State Information Jun Zhang, Marios Kountouris, Jeffrey G. Andrews, and Robert W. Heath Jr. Abstract This paper proposes an adaptive multi-mode transmission strategy to improve the spectral efficiency achieved in the multiple-input multiple-output (MIMO) broadcast channel with delayed and quantized Nettet1. mar. 2016 · These works in [10-12] are based on the case where the instantaneous channel state information (CSI) is known at the transmitter. For the transmitter with only the statistical CSI, the optimal precoder for finite-alphabet inputs over MIMO channels can be obtained by using the algorithm developed in [ 13 ].

NettetHistory Early research. MIMO is often traced back to 1970s research papers concerning multi-channel digital transmission systems and interference (crosstalk) between wire pairs in a cable bundle: AR Kaye … Nettet28. mai 2024 · May 28, 2024. In this post, we describe a novel state channel construction called virtual channels that uniquely enables use cases like paid file torrenting (check … Nettetavailability of instantaneous channel state information (CSI) at the base station (BS). However, in frequency division duplex (FDD) systems, no existence of channel reciprocity leads to the difficult acquisition of accurate CSI at the BS.
